With the introduction of multilib ebuilds, there is a question I'm not sure about: Some ebuilds call gen_usr_ldscript to move libraries to /, fine. However, libraries for the non native ABI have nothing to do in /: they are useless there. So far I've been making those calls conditional to 'multilib_is_native_abi' but maybe it would make more sense to simply no-op gen_usr_ldscript if '[[ ${ABI} != ${DEFAULT_ABI} ]]'; it should work but I'm not 100% sure. What I'm asking is: Please take a decision either to change gen_usr_ldscript or not so that I can know what is the proper way.
I was actually thinking something similar as well since I've been making the calls conditional as well.
I'm thinking that if the council decides we do not support separat /usr without an initramfs or an early boot mechanism like busybox[sep-usr], we can make it a complete no-op on Linux in the future. Thoughts? William

i think getting it out of the way now for non-native ABIs makes sense. it's orthogonal to the /usr merge and applies to all systems, not just Linux.
i've implemented this here: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=838c3028555eb9d8f12017dcf43f0c7b0c8af90f it's contingent upon the ebuild using multilib-minimal eclasses, but that doesn't seem like a big deal as every multilib-enabled ebuild at this point is doing just that.
